Description

Adjacent Network Approaches and Devices

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcasting receiver such as a digital television (DTV) or a digital terrestrial television (DTTV). More specifically, the present invention relates to a neighboring network that can be received in a currently received network. The present invention relates to a method and apparatus for accessing an adjacent network so that a user can easily access the same.

At present, the standardization of digital TV broadcasting is progressing at a rapid pace, among which specific services have begun. In the United States, digital broadcasting services by DirecTV and USSB entered commercialization in June 1994, and in Europe in December 1993, a joint project called EP-DVB (European Project for Digital Video Broadcasting) began. The standardization of digital TV broadcasting including CATV has been promoted. In such digital broadcasting, a table for program related information is defined, and each set implements a channel list including each channel number, channel name, program name, and the like for all channels that can be received. The implemented channel list is displayed on the TV screen according to the user's request and used for the user's channel selection and other services.

However, in a digital broadcasting receiver such as DTV or DTTV, which receives such a digital broadcast, there may be a case where a channel belonging to an adjacent network may be received instead of a single-network. For this reason, a channel list implementation of each network for a plurality of networks that can be received on a single set has been required.

Accordingly, an object of the present invention is to provide a neighboring network access method that can implement a channel list for the channels belonging to the neighboring network that can be received from the currently received network in view of the above.

Another object of the present invention is to provide an apparatus implementing the aforementioned neighbor network access method.

The neighbor network access method of the present invention for achieving the above object is, in the neighbor network access method in the digital broadcasting receiver, (1) storing the network information that can be currently received, (2) according to the user input Displaying a network change menu for access to a neighboring network from a currently received network based on the stored network information, and (3) parsing a network selected from the displayed network change menu. And (4) constructing a channel list for the channels receivable in the corresponding network according to the analysis result.

A neighboring network access device for achieving another object of the present invention is a device for accessing a neighboring network in a digital broadcasting receiving apparatus, comprising: a storage unit for storing currently-receivable networks in a database form, and an input TS form. An analyzer for analyzing the data and extracting the SI / PSI, and outputting a network change menu for the user to select one of the networks stored in the storage unit according to a user input, and extracting the network in response to the network selected by the user And a control unit for configuring a channel list for the channels receivable from the received SI / PSI, and a display unit for displaying a network change menu and a channel list configured under the control of the control unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a neighboring network access device according to the present invention. 1 is an analyzer for parsing data input in the form of a transport stream (TS) to extract service information (SI) / program specific information (PSI); 11), the control unit 12 for extracting the currently receivable network information from the extracted SI / PSI and constructing a channel list for the receivable channels in the network selected by the user, and the extracted network information and for each network A storage unit 13 for storing the configured channel list is provided. The apparatus of FIG. 1 also includes a display unit 14 for displaying a network change menu on a TV screen so that a user can access a neighboring network that can be received from a currently received network under the control of the controller 12, and the controller 12 A / V decoder 15 for outputting video and audio so that a user can watch a broadcast program by decoding the lowest program of the channel having the most programs among the channels receivable in the network while constructing the channel list It is provided. The operation of the adjacent network access device of FIG. 1 having such a configuration will be described.

Upon installation of a TV set or by user selection, the control unit 12 analyzes the currently receivable network through the analyzer 11. The control unit 12 stores the analysis result of the analyzer 11, that is, the network information which can be currently received, in the storage unit 13 in a database form. On the other hand, if there is a user input for accessing a receivable adjacent network other than the currently received network, the control unit 12 displays the network change menu on the TV screen through the display unit 14. That is, the display unit 14 displays the network information stored in the storage unit 13 on the TV screen under the control of the control unit 12 so that the user can select any one of the networks that can be received. The user selects the desired network by viewing the network change menu displayed on the TV screen and manipulating the key metrics attached to the remote control or the set. The control unit 12 receives TS-type data received on the network selected by the user. The analyzer 11 extracts the SI / PIS by analyzing the input TS data. In each program number, the PIS has a table form of packet information constituting the program, bit strings such as video, audio, and additional data, decryption information for unscrambled pay-TV, and physical information about the transmission path. The control unit 12 constructs a channel list of all channels receivable on the network using the extracted SI / PIS. The channel list includes various channel information such as channel numbers and broadcast station names corresponding thereto. The configured channel list is stored in the storage unit 13. The A / V decoder 15 receives and decodes a program of a channel meeting a condition set as a default in the network so that the user does not get bored while the controller 12 configures the channel list for the adjacent network. The video is output on the TV screen so that the video can be viewed, and the audio is output through a speaker (not shown). In the present embodiment, the lowest program of the channel having the most programs among the channels receivable in the current network is set as a default, but is not limited thereto.

As described above, the method and apparatus for accessing a neighboring network of the present invention can display a menu for changing a network on a TV screen so that a user can easily access a neighboring network that can be received from a network that is currently being received. Construct a channel list of the receivable channels in each network for the networks to provide the user with the receivable network and the receivable channel information of the network, so that the user does not get bored by watching the broadcast program while constructing the channel list. Has the effect.
